The free end of the cylinder .T is
v supported movably in the bifurcated head L of another standard M, which is, however, movable around its'own axis, its lower end being stepped loosely into a bearing N in the bottom of the box, while its upper end is inserted loosely through a guide bracket or bearing O, projecting inwardly from the adjacent side of the box, so that said standard M, with its forked head L, is free to revolve in its bearings N and O. This movable or revolving standard L M forming, as we have seen, a bearing or support for the outer end of the movable cylinder, is provided near its lower end with four arms or projections P, arranged in a horizontal plane at right angles to one another. Each of these arms consists, in the present illustration of this part of our invention, of j two plates or strips of steel or other tough and elastic metal (see Figs. G and l0) a and ZJ, the inner vends of which are fastened in the revolving standard M, while their ilarin or divergin g outer ends are bent toward and overlapping each other endwise, and c0nnected movably by a headed bolt c, fastened to one of the arms Ct and projecting through a slot CZ in the other arm b. rlhe arms a and b have placed between them at their widest part, or point of greatest divergence, a stout i spiral spring e, which acts as a buffer or cushion, as will be hereinafter described.
The upper ends of the forked head L are rounded, as shown at Z, and are also rounded or beveled on their inner sides, as shown at fm, so that when the standard M, with its forked head or saddle L, is given a quarter of a turn it will lift the free end of the cylinder up into an inclined position, as shown by the dotted lines-z'. e.. inclined from the saddle L toward the fixed bearing G. lVhen, on the other hand, the apparatus is in its normal po* sition, cylinder J will be inclined in the opposite directioinviz: the end resting in the saddle L is then the lowest point and its hinged end the highest, which position is illustrated in full line on the drawings. Vhen the cylinder is in the latter or normal position, the interior ball or sphere K will of course rest in the lowest part of the cylinder just above the saddles; but when the cylinder is tilted into the other position (shown in dotted lines) bya one-quarter revolution of the saddle then the ball will by its own gravity roll down into the other end, which is then the lowest. VVithin this end of the eylinderare placed two insulated metallic contact-plates Q and R, one of which Q is connected byan insulated wire q with the line-wire within the insulated cable D, while the other R is similarly connected by an insulated wire r with the appropriate naked.conductingstrip F. Under normal conditions, therefore, the current cannot pass from cable D into strip F, but when the cylinder is raised or tilted the ball, rolling down into that end, will rest or bear against and establish metallic connection between the two contact-plates Q and R, thus permitting the current to fiow from cable D through the wire q, contact-plate Q, ball K, plate R, and wire r to the naked strip F. The current is ,again broken or shut o the moment the free standard, a standard adapted to revolve around its own axis and provided with projecting arms or wings at its lower end, constructed as described, a bifurcated head or saddle, and a pivoted cylinder adapted to be moved or tilted in a vertical plane parallel to the sides of thebox, and provided with its appropriate contact-ball, contact-plates, and insulated wires connecting`- said plates with respectively the line-cable and the naked conducting-strip. rlhe only difference is that the position of this second cylinder with its appurtenances is reversed-4. c., both cylinders, while parallel to each other, tilt or swing in opposite directions when actuated or operated by their respective revolvingstandards M and saddles L.
Having in the foregoing described the construction of our apparatus, we shall no w proceed to explain its operation, which is as follows: Each car is provided at opposite ends with a downwardly-projecting arm or bar S, of such dimensions that it will enter and run freely in the slit inthe plate covering the conduit trough and boxes in substantially the same manner as the grip-levers used on cable cars. As the car is started along the track the forward arm S will strike the arms or wings P of the two revolving standards M M in the first box, and thereby give to each ot' these a one-quarter turn, which tilts their respective cylinders into the position shown in dotted lines, thereby closing the circuit on both sides between the pair of strips F F appertaining to the first box and its appropriate conduit-section. As these conducting-strips F and F are not continuous, but broken into lengths of appropriate size corresponding to the length or distance between the two depending arms of the cars, which are arranged endwise in close proximity to one another, as shown in Fig. l, it follows that only that particular length or section of strips F and F which appertains to that particular box is rendered active by the closing of the circuit between it and the line-cables, the connecting-strips over the remainder of the line being dead or inactive. The motor within the car is su pplicd with power from this act- IDO IIO

ive section just underneath the car by contact-brushes in the usual way, brushing against the strips, and as the car leaves the portion of track over this active section the rear arm S will in its turn strike the wings P, and thereby tilt the circuit-closing cylinders back into their normal position, thus shutting off the current from the line-cables to the conducting-strips. At the same moment the forward arm of the car will have reached and operated the apparatusin the next box, thereby rendering the next section of conducting'- strips F F active, and so on over the entire length of the line, the forward arm S opening and the rearward arm closing the circuit which renders active the appropriate pair of conducting-strips F and F appertaining to the particular length or section of track over which the car is moving and from which it is to take its power.
By constructing the operating` wings or arms P, as described, with the buffer-springs e they will receive the blows of the depending arms S without injury, and will also cause the standards M to revolve smoothlyhand easily and without jarring. By using' four of these wings upon the revolving standards instead of two, cars may be run forward or back upon the same track, as the apparatus may be operated from either side with equal facility and certainty of operation.
Ilavin thus described our invention, we claim and desire to secure by Letters Paten t of the United States l. In an electric railway, the combination, with two insulated conductors forming the electric circuit, of a series of conducting-strips, a cylinder connected with said strips and conductors and journaled at one end in a fixed support and its other end resting in a rotating support by which it is raised and lowered, a ball or sphere in said cylinder, actuated by gravity tol make electrical connection between the conductors and strips, and means by which the cylinder-support is rotated automatically, substantially as described.
